To increase the energy of the emitted electrons, the frequency of the incident light on the metal must be increased.
<h3>What is energy of emitted electron?</h3>
The maximum energy of an emitted electron is equal to the energy of a photon for frequency f (E = hf ), minus the energy required to eject an electron from the metal's surface, also known as work function.
Ee = E - W
<h3>Energy of the emitted electron</h3>
The energy of emitted electrons based on the research of Albert Einstein is given as;
E = hf
where;
- h is planck's constant
- f is frequency of incident light on the metal
Thus, to increase the energy of the emitted electrons, the frequency of the incident light on the metal must be increased.

Answer:
nothing
Explanation:
aslong as nothing falls off fhen the mass and weight wont change
Explanation:
The ideal gas law or equation can also be reduced to the general gas law or the combined gas law.
Let us assume that n = 1;
From PV = nRT ideal gas law
= R (constant) if n = 1
Therefore, the combined gas law is;
The expression is a combination of Boyle's Law and Charles's law.

Answer:
Explanation:chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.
0.1125 moles
Total mass number of AlCl3 = 27 + (3x35.5) = 133.5
Number of moles equals mass divided by mass number
10:133.5=0.075 ( this is the number of moles of AlCl3)
To get the number of moles of Cl2, look at the coefficient of both AlCl3 and Cl2
0.075x3:2=0.1125 moles
I hope this helps
